- GRATE FOR GAS-PRODUCERS AND CARBONIZING PLANTS.

ea ers.

To all w 7mm it may concern Be it known that 1, JOHN WELLS, a subject of the King of Great Britain, of 36 Sharia Falalri, in the city of Cairo, Egypt, have invented new and useful Improvements in Grates for Gas-Producers and Carbonizing Plants, of which the following is a specification.

This invention relates to grates for gas producers, carbonizing plants, boilers and the like.

According to this invention, the grateframe is pivoted to turn about a horizontal axis and is balanced so that it may be readily inclined as required, for example, in accordance with the nature of the material consumed, or turned down into a position permitting the rapid removal of any clinker which may be formed thereon. Means are also provided for securing the grate in the position to which it has been adjusted. Provision is also made for adjusting the position of the grate as a whole by moving its axis of oscillation laterally, so as to increase or diminish the area of the space through which the ashes pass to the ash-pit.

In the accompanying drawing Figure '1 is a transverse section along the line 1-1 of Fig. 2 of a grate constructed according to my invention and as applied to a gas producer, looking in the direction of the arrows indicated in Fig. 2, and

l 2 is a front elevation thereof.

A is the discharge aperture of the gas produ'rr and B a pivot-shaft adapted to rest in one of a series of pairs of recesses C formed in the base-frame A of the producer. ()n the pivot-shaft B are mounted cheeleplates l) which together with a bar E and the shaft form the frame on which the fire bars F, F are supported. The cheek-plates D are provided with downward extensions D con-- nected by a bar G to which are attached or suspended one or more balance weights H accbrdingz to the weight of the grate and of the average load thereon.

(me or both of the cheek plates D is provided with an eye J arranged opposite a perforated sector K, secured to the base frame A, .so as to permit of the grate being secured at any desired angle by means of a pin L extending through the eye J and through the corresponding hole in the sector K.

Specification of Letters Patent.

Application filed November 1, 1919.

Patented May 31, 1921.

Serial No. 335,080.

The fire-bars F, F are shown provided with recesses M, M at each end to fit over the shaft B and the bar E.

N is a shaft which is rotatably mounted in bearings O at the sides of the roducer and has mounted on it paddles P, 3 for facilitating the discharge of ashes from the grate. This paddle-shaft is shown driven by means of a chain Q and sprocket-wheels R, S from a shaft T provided with a crank-handle for turning it. I

The operation of my improved grate is as follows With the grate in its most nearly vertical position, that is to say at the steepest inclination, the producer Would operate as any other form of producer with an inclined grate. When, however, fuel is used containing a big percentage of ash the top end of the grate may be lowered to any position on the sector K and thus put the grate in Such a position that clinker or accumulation of ashes may be rapidly and easily forced down into the ashpit U after which the grate may be allowed to resume'its original position. It is found with certain classes of fuel, especially fuels with a low ash content, that better results are obtained with the grate set in a position nearly approaching horizontal.

WVhat I claim as my invention and desire to secure by Letters Patent is:

In a gas producer, a furnace body, an inclined grate arranged within the furnace body and pivotally supported therein at its rear end, means for adjustably liolding said rear end of the grate in diiferenthorizontal positions for spacing the grate from the rear wall of the furnace body, means for adjustably supporting the forward upper end of the grate whereby said grate may be sup ported at different angles in the lowerporion of said furnace body, and a paddle facilitating the discharge of ashes therefrom, substantially as described.

JOHN WELLS.
